How to I combine 2 curve points to create a mesh
Assuming you just want a plane the same shape as your current mesh:

In Edit mode, select Edge mode. Click one edge and shift-click the opposite one to create the outer edge. 'P' to separate the selection then go back to Object mode, select the edge, and back to Edit mode. 'A' to select all and 'F' to Fill. You then have a plane the shape of your original object.
